Добрый день! Подскажите, пожалуйста,
concentration indices - это индексы рассеивания?
Introduction: Vietnam has achieved considerable success in economic development, poverty reduction, and health over a relatively short period of time. However, there is concern that inequalities in health outcomes and intervention coverage are widening. This study explores if inequalities in reproductive, maternal, newborn and child health and nutrition changed over time in Vietnam in 1997-2006, and if inequalities were different depending on the type of stratifying variable used to measure inequalities and on the type of outcome studied. Methods: Using data from four nationally representative household surveys conducted in 1997-2006, we study inequalities in reproductive, maternal, newborn and child health and nutrition outcomes and intervention coverage by computing concentration indices by living standards, maternal education, ethnicity, region, urban/rural residence, and sex of child.

Заранее признательная за помощь!

"concentration indices - это индексы рассеивания?" - скорее наоборот, концентрации))))

* a 'concentration index (of sth)' = how concentrated/dispersed sth is, expressed as an index (=a measurement/statistic).
* 'concentration indices by living standards, maternal education [etc]' = concentration indices (according to/based on) living standards, maternal education [etc].
